To all whom it may concern.' f Be it knownl that I, HENRY C. BUNTING, a citizen ofthe United.y States, residing at Dunbar, in the county ofFayette and State of Pennsylvania, have invented ful Improvements in Hinge-Seat Gages, of which the following is a` specification.

new and userIhis invention relates to hinge seat gagesf of the type employed in the `operation ofi' forming hinge receiving mortises, and has for its objects to providea comparatively,t

simple, inexpensive device of this character adapted for measuringthe length, breadth and depth of the mortise to be formed, and one wherein the parts ofthe gage may be conveniently adjusted to V.accord with mortises of varying dimensions.

With these and otherobjects in view, the

invention comprises the novel features lof construction and combination ofparts more fully hereinafter described.

In the accompanying drawings: Figure 1 gage embodying is a perspective view of` a the invention. Fig. 2 is a bottom plan view of the same. Figs.A 3 and 4 are detail, Vsectional views taken respectively `on the lines 3 3 and 4-4 of Fig. 1.--,Fig. 5 is a detail view of one of the clamping screws.

Referring to the drawings, it will be seenV that the` gage embodiesanelongated base member or'platein which is formed a transversely extending groove or channel 3 and a longitudinally extending slot 4 of a length equaling :substantially one-half the length of thek plate and arranged from the channel 3, while inscribed on the upper face of the plate at one side of the slotY 4 is a graduated scale 5 denoting inches and fractions thereof.

Projecting from the base plate 1 is a pair of relatively spaced end gage members or arms 6 Vand 7, of which the former isprovided at its inner end with.` a foot 8 slidably arranged in the'channel 3and` to extend transversely of the base platewhile the arm Y 7 is in like manner provided at its inner end with a foot 9 extended transversely of and arranged to bear on the upper face of the plate, at the lower face there is disposed in line with the foot 9 a bearing piece 10 having a slot 11 through which a clamping Yscrew 12 is entered for engagement with the arm 7. The base plate 1 is provided withy a transverse slot 13 disposed vcentrally ofthe atfa point remote' channel 3 to receive a clamping screw 14 engaged with the inner end of arm 6.

Adjustably mounted on the arms 6 and 7 isfa side gage member or bar 15 extended longitudinally in parallel relation with the plate and having at one end an opening 16 g adapted toaccommodate the arm 6, there beftended transversely through the arms and bar and equipped with adjustable clamping nuts 22, there being formed on the screw 21, which during movement of the arm 7 travels back and forth in the slot 18, an elongated head 23 formed to fit in the slot 18 for fixing the screw against rotation.

Y In practice, the arm 7 may, by loosening the screw 12 and nut 22, be moved toward or from the arm 6 to accord with the le'ngth of Y the hinge leaf, while the bar 15 may, by loosening the nuts 22, be moved back or forth toward the base plate 1 to accord with the width of the hinge leaf, after which the clamping screws are tightened for iixing the parts in adjusted position.

In using the gage, it is laid flat on the door or door frame to be mortised and lines drawn at, the inner edges of thearms 6 and 7 and bar 15 to show the length and breadth of the mortise, the depth of which will correspondV with the distances between the bases of the arms and the front edge of the plate `1 which accords with the standard thickness of the hinge leaves.

Having thus described my invention, what yI claim is:

1. A gage ofthe class described comprising a base plate having a longitudinally-extendino slot at one end and a transverselyextending slot at the opposite end, a pair of arms projecting perpendicularly from the top of the plate and each provided with a lon` gitudinally-extending slot, clamping means for the arms and including screws passing vided at their inner ends with cross heads extended transversely of the plate, said arms being adjustable in a direction transversely of the plate for projecting the cross heads beyond one edge of the latter, and one of the arms being movable longitudinally of the plate toward and from the other, means for fixing the arms in adjusted position, a gage bar adjustably mounted on the arms for movement toward and from the base plate, and means for xing the bar in adjusted positions.

3. A gage of the ela-ss described comprising a base plate, an arm secured thereto for lateral adjustment, a second arm, means for securing the second arm to the base plate and providing for adjustment of the arm both longitudinally of and transversely to the base plate, a gage bar, means for connecting the bar with the first-mentioned arm for adjustment toward or away from the base plate, and means connecting the bar with the second arm to permit of relative adjustment.

In testimony whereof, I alix my signature in presence of two witnesses.

HENRY C. BUNTING.
